Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78402, here are decompositions:
- 61 + 78341 = 78402
- 101 + 78301 = 78402
- 173 + 78229 = 78402
- 199 + 78203 = 78402
- 211 + 78191 = 78402
- 223 + 78179 = 78402
- 229 + 78173 = 78402
- 239 + 78163 = 78402
Showing the first eight; more decompositions exist.
